Yes. I run into this when using corel draw to lay out PCBs. There is a 
tool online to convert corel draw to whatever is used by PCB people - 
Gerber?

( I use corel because the more modern packages require that you define 
every single component before you start which takes days).

The converter ignores fonts and line thicknesses - it only understands 
filled outlines - so I have to convert everything to 'curves' ..

But that's the joy of CADS isn't it? So many standards to choose from.
